Description: The report is organized into three parts. The first provides a brief overview of the role of the agriculture and forestry sectors within the broader climate change debate, describing available estimates of current GHG emissions and carbon sequestration in the farm and forestry sectors. The second describes available data and information on the potential for carbon storage (tonnage) by type of farming and forestry activity, and presents available estimates of the carbon sequestration potential in these sectors. The final part discusses some of the limitations of available estimates of GHG mitigation potential in the agriculture and forestry sectors, focusing on recent policy and market changes and other types of modeling uncertainties that could limit the accuracy of available mitigation projections.

Description: This report provides background on aviation emissions and the factors affecting them; it discusses the tools available to control emissions, including existing authority under the Clean Air Act and proposed economy-wide cap-and-trade legislation; and it examines international regulatory developments that may affect U.S. commercial airlines.

Description: This report introduces the reader to fundamentals of the climate change issue. Part One summarizes current understandings and controversies concerning the science, economics, international cooperation, and other aspects of the climate change policy problem. Part Two is a brief update on the status of domestic and international policies. Part Three outlines the policy toolbox seen as being available to policymakers to address the challenge as they define the emerging legislative agenda.

Description: This report begins with an overview of the fundamental choices involved between a cost (tax) and a quantity (cap) control instrument. This includes a discussion of policy tools that could be employed to bridge the gap between a carbon tax and a cap-and-trade program. Following this overview, the report analyzes the potential advantages and disadvantages of a carbon tax. In many cases, carbon tax attributes are compared with those of a cap-and-trade program. The next section discusses implementation issues for a carbon tax, including where to apply the tax, at what level to set the tax, and options for distributing the tax revenues. The final section provides conclusions.

Description: This report examines the current effort to develop technology that would capture CO2. First, the paper outlines the current status of carbon capture technology. Second, the paper examines the role of government in developing that technology, both in terms of creating a market for carbon capture technology and encouraging development of the technology. Finally, the paper concludes with a discussion of implications of capture technology for climate change legislation.

Description: This report reviews the nature of EPA's, California's, and other states' authority to regulate emissions from mobile sources, the applicability of that authority to GHGs, and issues related to the California waiver request.

Description: This report provides information regarding pollution from ships and port facilities; discusses some of the measures being implemented and considered by local, state, and federal regulatory agencies; discusses the efforts to ratify and to strengthen Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL); and describes legislation in Congress to control emissions from ships by amending the Clean Air Act (CAA).

Description: This report discusses the potential impact on communities attempting to achieve National Ambient Air Quality Standards (NAAQS) and the impact on mercury emissions could be substantial, and has prompted some to call for congressional action to address the issue.
